I guess i just understand why there can't be Magic life and mana leech?

I assume it's been intentionally left out as some kind of penalty for balance.

just don't understand why

Mages have less defense/life points ... if a mage needs life leech he is just about dead. Don't understand the problem with it.

There is both life and mana leech available for spells via the support gems.

The Life gain on Hit support, however, does not work on spells. This is at least partially because spells, in general, can hit a lot more things per cast than attacks, and balancing around them would mean that this was a strength gem that was only useful with big area spells.
